An IP address (Internet Protocol address) is a unique numerical label assigned to every device connected to a network. Think of it as your device's mailing address on the internet.
IPv4 vs IPv6
There are two main versions of IP addresses in use today:
- IPv4 uses a 32-bit format like
192.168.1.1and supports roughly 4.3 billion addresses. - IPv6 uses a 128-bit format like
2001:0db8:85a3::8a2e:0370:7334and supports a virtually unlimited number.
Why Should You Care?
Your IP address can reveal your approximate location, your ISP, and whether you're connecting through a VPN or datacenter. Websites and services use this information for:
- Geo-targeting — showing you region-specific content
- Security — detecting suspicious login attempts
- Analytics — understanding where their traffic comes from
